Python 如何从Flask Docker容器访问MongoDB Atlas Service？

我对接了我的

React

+

Flask

+

Nginx

应用程序，并在我工作的一个内部服务器中提供了它

我使用

mongoatlas

作为数据库，并使用

Flask

中的

pymongo

创建API

我的烧瓶应用程序的初始部分如下所示：

from flask import Flask, render_template, request, jsonify
from flask_cors import CORS
from bson.objectid import ObjectId
import pymongo
import json
import ssh
import OpenSSL
import pprint

application = Flask(__name__)
cors = CORS(application)

client = pymongo.MongoClient("mongodb+srv://...")

db = pymongo.database.Database(client, '...')
col = pymongo.collection.Collection(db, '...')

# some parts are written as `...`

#Using ubuntu as our base
FROM ubuntu:latest

#Install commands in ubuntu, including pymongo for DB handling

RUN apt-get update -y
RUN apt-get install -y python3 python3-pip python3-dev build-essential


#Unsure of COPY command's purpose, but WORKDIR points to /backend
COPY . /backend
WORKDIR /backend/

RUN pip3 install --proxy <proxy_settings_for_my_workplace> -r requirements.txt
RUN python3 -m pip install --proxy <proxy_settings_for_my_workplace> pymongo[srv]

ENV HTTPS_PROXY=<proxy_settings_for_my_workplace>
ENV HTTP_PROXY=<proxy_settings_for_my_workplace>

#Run order for starting up the backend
ENTRYPOINT ["python3"]
CMD ["app.py"]

Flask

应用程序的

Dockerfile

如下所示：

from flask import Flask, render_template, request, jsonify
from flask_cors import CORS
from bson.objectid import ObjectId
import pymongo
import json
import ssh
import OpenSSL
import pprint

application = Flask(__name__)
cors = CORS(application)

client = pymongo.MongoClient("mongodb+srv://...")

db = pymongo.database.Database(client, '...')
col = pymongo.collection.Collection(db, '...')

# some parts are written as `...`

#Using ubuntu as our base
FROM ubuntu:latest

#Install commands in ubuntu, including pymongo for DB handling

RUN apt-get update -y
RUN apt-get install -y python3 python3-pip python3-dev build-essential


#Unsure of COPY command's purpose, but WORKDIR points to /backend
COPY . /backend
WORKDIR /backend/

RUN pip3 install --proxy <proxy_settings_for_my_workplace> -r requirements.txt
RUN python3 -m pip install --proxy <proxy_settings_for_my_workplace> pymongo[srv]

ENV HTTPS_PROXY=<proxy_settings_for_my_workplace>
ENV HTTP_PROXY=<proxy_settings_for_my_workplace>

#Run order for starting up the backend
ENTRYPOINT ["python3"]
CMD ["app.py"]

使用ubuntu作为我们的基础 来自ubuntu：最新版本 #在ubuntu中安装命令，包括用于DB处理的pymongo 运行apt获取更新-y 运行apt get install-y python3 python3 pip python3 dev build-sential #不确定COPY命令的用途，但WORKDIR指向/backend 抄袭/后端 WORKDIR/后端/ 运行pip3安装--proxy-r requirements.txt 运行python3-mpip安装——代理pymongo[srv] 环境HTTPS_代理= ENV HTTP_代理= #运行启动后端的命令 入口点[“蟒蛇3”] CMD[“app.py”] 一切都很好地建立起来了。但是，在它启动后，我可以很好地访问前端部件，但我后端的日志显示一个错误，显示：

pymongo.errors.ServerSelectionTimeoutError:.mongodb.net:27017:超时，.mongodb.net:27017:超时，.mongodb.net:27017:超时

我假设这不起作用，因为我无法使用

pymongo

通过Flask访问

Mongo Atlas

，我试图将Flask映像的IP添加到

Mongo Atlas

的网络访问控制台

但很明显，这是行不通的

我如何解决这个问题？

你的Mongo Atlas在哪里？我使用的是云服务：你需要将你的作品的互联网网关IP白名单，而不是docker端的任何内容。
